I'm pretty new to Tekkit, and I spawned in a Taiga (snowy forest of spruce) biome. I think I turned large biomes on, just by the size of it and the nearby jungle. I found plenty of all of the Tekkit ores, but no rubber trees anywhere, using all the hints to find them. The jungle biome has plenty of the RedPower trees, but I need rubber to convert the wood in those to rubber, I believe. Please help.
